dm368 ecc 移植ubifs到dm368成功(5)

/* Mask to zero out thechip options, which come from the id table */

#defineNAND_CHIPOPTIONS_MSK(0x0000ffff &~NAND_NO_AUTOINCR)

/* Chip can not autoincrement pages */

#define NAND_NO_AUTOINCR0x00000001

找到问题了，解决办法就有了，注释掉红色的那行代码，就是他把NAND_NO_SUBPAGE_WRITE给丢掉了。

//chip->options &=~NAND_CHIPOPTIONS_MSK;

再重新编译下载kernel，问题搞定了！

再次启动开发板，加载ubi，一切正常了。
